It depends on how long gas lasts. Some cars have low mileage and some have high milege. If you have a Toyota prius(which is a hybrid) is aout 45 miles per gal. so each gal lasts for every 45 miles you travel.
Depends on the area of the building you put it in or if its outside it doesnt last long.
When it comes to home power generation, per me, gas driven generators are the best choice. Lasting of Gas depends upon the usage, size of the generator. If the size is small it will last long where as if it is heavy and you are using it extensively it will last less.
for some 50 or 60 years
anywhere from 50-100 years
About 18 miles!
The gas in a V8 car will last varying amounts of time. One tank will last about a week if you are only driving 30 miles each day.
The gas seeps out slowly but you should have it refilled every couple of years
It depends on the rate at which you are consuming the gas.
They usually last forever if you replace the engine and replace parts!It will be bad on Gas Milage though......
I just started and ran a 79 T-Bird for an hour and fifteen minutes with gas that was last put in in (I am not making this up) April of 2004.
Batteries should be changed every 6 months. Some can last up to a year.
A furnace should last 35 years, many companies offer a ten-year warranty.
